What RSS did was create and nurture an information landscape based on the authority of the author. It allowed those authors to gain such authority both within and outside the media infrastructure of that time. But it also gave rise to a separate wave of authority, that of the reader, the analyst, the commentator, and so on. The blog post maintained its central role even as it absorbed every other document and media type, and it was joined with a seat at the table by a metadata stream of attention and gestures. Suddenly the root object was the @mention, whether a Tweet by the author, a retweet by a reader, an @mention of other such authorities, the implicit clouds of such signals.
I really liked this paragraph!
